I just bought a 2011 X5-50i the guy I bought it from didn***8217;t take great care of the rig. I also didn***8217;t know anything about the N63 problems and thought I***8217;d be crazy to pass up on such an amazing looking and driving vehicle. I noticed that after driving for an hour or so that I could smell oil burning. So I popped the hood and saw that the two oil crank case ventilation hoses were broken and leaking oil. I fixed them plus the turbo coolant lines where the Y fitting was basically disintegrated. Thanks to these forums I found the problems and fixed them but I got a code the other day a PO52B. I cleaned the Vanos system intake and Exhaust selanoids. And it seemed to work but still it starts a little rough every once and awhile. Should I just buy a new camshaft position sensor???
